Title: Elastic surface wave filter
Inventor: KODAMA RIICHI
IPC: H03H9/02
Filed: 1978-11-27
Abstract: PURPOSE:To ensure the sufficient compensation for the diffraction effect of the elastic surface wave and thus to obtain the excellent filter properties by installing the 3rd electrode similar to transducer TRD with the cross-width weight between such TRD and the input/output TRD of the uniform cross width. CONSTITUTION:Input TRD11 with the cross-width weight plus its opposing output TRD12 of the uniform cross width are provided on the piezoelectric substrate. Then power source 13 is connected to TRD11 via input resistance 14; while load resistance 15 is connected to TRD12 each. And 3rd electrode 16 which is the similar type to TRD11 is installed to the surface wave propagation path between TRD11 and 12. As TRD11 features the split-type, electrode 16 also uses the split-type. While TRD12 uses the solid-type. In the case of the split-type electrode, the mutual reflection is negated at the electrode edge by arranging 1/8-input electrode width 21 and 5/8-input electrode width 22 alternately. Thus the diffraction effect can be compensated to obtain the excellent filter properties.

Title: Digital arithmetic circuit
Inventor: OMOTANI YOSHIRO
IPC: G06F7/552
Filed: 1984-07-13
Abstract: PURPOSE:To obtain a numerical value proportional to the k-root (k: a real number larger than 1) of the input value without increasing the number of memory elements and by reducing the quantizing error of the output value that is produced when the input value is small. CONSTITUTION:When the output value Y proportional to the k-root of the input value X is obtained in the form of the output value Y, an input level deciding circuit 4 decides the level of the value X. Based on the result of said decision, an input level converter 5 converts an input level into the numerical value within a fixed range. An input data compressing circuit 6 reduces the numerical value that can be obtained by the input value converted into the numerical value within a fixed range. Thus the numerical value that can be obtained by the input value of a k-root arithmetic circuit 7. Then the number of memory elements is reduced as compared with a conventional table reference arithmetic system. Furthermore, no quantizing error is produced unlike said table reference arithmetic system since the value X is converted into an area free from the quantizing error with the small input value. This attains a k-root operation.

Title: Unnecessary operation preventing method of protective relay for alternating current feeder
Inventor: MOCHINAGA YOSHIFUMI
IPC: H02H7/045
Filed: 1992-05-14
Abstract: PURPOSE:To prevent unnecessary operation of a protective relay by subtracting no-load exciting rush current of a paper transformer for a car at the time when an electric rolling stock passes a different power change-over section from input of the protective relay by way of detecting it by a current transformer for equipment inserted into the change-over section. CONSTITUTION:By inserting an instrument current transformer 28 for equipment into a different power change-over section 8 before a transforming station for an electric railroad, a no-load exciting rush current Isn of a car transformer which generates a large value when an electric rolling stock 16 passes the change-over section 8 is measured. This current Isn is, for example, connected in parallel to an auxiliary CT 30 in reverse polarity to a trolley line side CT 11 by reducing it down to a more suitable multiplying factor 1/m times. Thereby, an input current Isy seen from a protective relay becomes Isn=(IT+IF)-Isn/ m. IT is a T phase current of a transformer current, and IF shows a F phase current. In this way, depending on whether the no-load excitating rush current Isn input to the protective relay becomes small in appearance or not, it is possible to prevent unnecessary operation of the protective relay.

IPC: B22D11/055
Filed: 1980-10-22
Abstract: PURPOSE: To obtain an ingot having smooth surfaces free from any surface defect by incorporating heating elements in the outlet side wall of a mold.  
     CONSTITUTION: A mold 1 has heating elements 2. In starting melting and casting, a dummy bar 5 is located at the bottom end of the mold 1, after which metallic granules 4 are supplied with a continuous supply device 3 for the same into the mold 1, where they are heated to melt. Under cooling with the cooling water 7 injected from spray nozzles 6, the bar 5 is lowered by pinch rolls 8. The solidified shell 10 of cast metal is formed by controlling the height of the molten metal 9 in the mold, the inside wall surface temp. at the outlet of the mold, the descending speed of the bar 5, and the supply rate of the granules 4. As the bar 5 descends, the shell 10 grows to form an ingot 11. At this time, it is important to control these in such a way that the molten metal 9 does not form the shell 10 along the side walls in the mold and forms the shell quickly in the outside of the mold outlet. To this end, the inside wall surface temp. at the mold outlet is maintained at above the solidifying temp. of the cast metal by the heating elements 2.
